How to convert String to Date Format

To convert a string to date, Java 8 provides DateTimeFormatter.ofPattern method in its java.time package.

package com.techstackjournal;

import java.time.LocalDateTime;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;

public class StringToDate {

	public static void main(String[] args) {

		String str1 = "04-18-2020 20:50:30 +05:30";
		ZonedDateTime zonedDateTime1 = ZonedDateTime.parse(str1, DateTimeFormatter.ofPattern("MM-dd-yyyy HH:mm:ss XXX"));
		System.out.println(zonedDateTime1);

		String str2 = "04-18-2020 20:50:30 +0530";
		ZonedDateTime zonedDateTime2 = ZonedDateTime.parse(str2, DateTimeFormatter.ofPattern("MM-dd-yyyy HH:mm:ss ZZ"));
		System.out.println(zonedDateTime2);

		String str3 = "04-18-2020 20:50:30 -04";
		ZonedDateTime zonedDateTime3 = ZonedDateTime.parse(str3, DateTimeFormatter.ofPattern("MM-dd-yyyy HH:mm:ss X"));
		System.out.println(zonedDateTime3);

		String str4 = "04-18-2020 20:50:30 -04:30";
		ZonedDateTime zonedDateTime4 = ZonedDateTime.parse(str4, DateTimeFormatter.ofPattern("MM-dd-yyyy HH:mm:ss [XXX][ZZ][X]"));
		System.out.println(zonedDateTime4);

		String str5 = "04-18-2020 20:50:30 America/Montreal";
		ZonedDateTime zonedDateTime5 = ZonedDateTime.parse(str5, DateTimeFormatter.ofPattern("MM-dd-yyyy HH:mm:ss VV"));
		System.out.println(zonedDateTime5);
		
		String str6 = "04-18-2020 20:50:30";
		LocalDateTime localDateTime1 = LocalDateTime.parse(str6, DateTimeFormatter.ofPattern("MM-dd-yyyy HH:mm:ss"));
		System.out.println(localDateTime1);

	}

}

Output:

2020-04-18T20:50:30+05:30
2020-04-18T20:50:30+05:30
2020-04-18T20:50:30-04:00
2020-04-18T20:50:30-04:30
2020-04-18T20:50:30-04:00[America/Montreal]
2020-04-18T20:50:30
